Method Detail

get

public double get(int i,
                  int d)

Description copied from class: KDTreePositions

Get the coordinates of the node i in dimension d.

Specified by:

get in class KDTreePositions

Returns:

the coordinate

asFlatArray

public double[] asFlatArray()

Description copied from class: KDTreePositions

Get positions of points in the tree as a flat double[] array where positions[d + i*n] is dimension d of the i-th point.

For serialisation and usage by the tree.

Internal storage may be a NESTED double[][] array. In this case, flatPositions() returns null.

Specified by:

asFlatArray in class KDTreePositions

asNestedArray

public double[][] asNestedArray()

Description copied from class: KDTreePositions

Get positions of points in the tree as a nested double[][] array where positions[d][i] is dimension d of the i-th point.

For serialisation and usage by the tree.

Internal storage may be flattened into single double[] array. In this case, the nested double[][] array is created here.

Specified by:

asNestedArray in class KDTreePositions

createBoundingBox

protected RealInterval createBoundingBox()

Specified by:

createBoundingBox in class KDTreePositions

layout

public KDTreePositions.PositionsLayout layout()

Description copied from class: KDTreePositions

Get the internal layout of positions.

Positions are stored in either FLAT or NESTED layout. With NESTED layout, positions are stored as a nested double[][] array where positions[d][i] is dimension d of the i-th point. With FLAT layout, positions are stored as a flat double[] array, where positions[d + i*n] is dimension d of the i-th point, with n the number of dimensions.

Specified by:

layout in class KDTreePositions
